Stachydrine
Proline betaine is an osmoprotective compound found in urine. It is thought to serve an osmoprotective role for the kidney. Proline betaine is a glycine betaine analogue found in many citrus foods. Elevated levels of proline betaine in human urine are found after the consumption of citrus fruits and juices (PMID: 18060588). Proline betaine is a biomarker for the consumption of citrus fruits. Alkaloid from Citrus spp Medicago sativa and Stachys subspecies(alfalfa). L-Stachydrine or also called proline betaine is a biomarker for the consumption of citrus fruits. L-Stachydrine is found in many foods, some of which are capers, pulses, lemon, and alfalfa. Proline betaine, also known as stachydrine, belongs to the class of organic compounds known as proline and derivatives. Proline and derivatives are compounds containing proline or a derivative thereof resulting from reaction of proline at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. Proline betaine exists in all living organisms, ranging from bacteria to humans. Proline betaine is found, on average, in the highest concentration within capers (Capparis spinosa). Proline betaine has also been detected, but not quantified in, several different foods, such as soy beans (Glycine max), crosnes (Stachys affinis), domestic pigs (Sus scrofa domestica), limes (Citrus aurantiifolia), and triticales (X Triticosecale rimpaui). This could make proline betaine a potential biomarker for the consumption of these foods. Proline betaine is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a significant number of articles have been published on Proline betaine. Stachydrine is a major constituent of Chinese herb leonurus heterophyllus sweet used to promote blood circulation and dispel blood stasis. Stachydrine can inhibit the NF-κB signal pathway.

Vinylacetylglycine
Vinylacetylglycine is an acyl glycine. Acyl glycines are normally minor metabolites of fatty acids. However, the excretion of certain acyl glycines is increased in several inborn errors of metabolism. In certain cases the measurement of these metabolites in body fluids can be used to diagnose disorders associated with mitochondrial fatty acid beta-oxidation. Acyl glycines are produced through the action of glycine N-acyltransferase (EC 2.3.1.13) which is an enzyme that catalyzes the chemical reaction:. acyl-CoA + glycine < -- > CoA + N-acylglycine. Vinylacetylglycine is a human metabolite that had been identified in a GC/MS urine screen. Increased amounts of this metabolite in the urine has been linked to a metabolomic disorder termed Isovaleric acidemia. (Gas-Chromatographic Method of Analysis for Urinary Organic Acids. I. Retention indices of 155 metaboically Important Compounds; Kay Tanaka, David G. Hine, Agnes West-Dull, and Theodore B. Lynn.). Vinylacetylglycine is an acyl glycine.

Trimethadione
Trimethadione is only found in individuals that have used or taken this drug. It is an anticonvulsant effective in absence seizures, but generally reserved for refractory cases because of its toxicity. (From AMA Drug Evaluations Annual, 1994, p378)Trimethadione reduces T-type calcium currents in thalamic neurons, including thalamic relay neurons. It does so via the inhibition of voltage dependent T-type calcium channels. This raises the threshold for repetitive activity in the thalamus, and inhibits corticothalamic transmission. Thus, the abnormal thalamocortical rhythmicity, which is thought to underlie the 3-Hz spike-and-wave discharge seen on electroencephalogram(EEG) with absence seizures, is dampened.

6-oxopiperidine-2-carboxylate
6-Oxopiperidine-2-carboxylic acid, also known as 6-Oxo-pipecolinic acid, or 6-Oxo-piperidine-2-carboxylic acid, is associated with penicillin V in the production on Penicillium chrysogenum fermentations. Analysis of a 13C NMR spectrum of a concentrated broth from Penicillium chrysogenum fermentation revealed the presence of penicillin V and 6-oxo-piperidine-2-carboxylic acid(1) as the principal constituents. The latter lactam, identical to an authentic sample prepared by the cyclization of alpha-aminoadipic acid was present to the extent of 28 mol\\% of penicillin V. The lactam isolated form the broth was nearly racemic, having a slight excess of the L-isomer. This isolation provides further evidence regarding the biosynthetic precursors of the hydrophobic penicillins. (PMID: 6788737

Sedridine
Sedridine is a member of the class of compounds known as piperidines. Piperidines are compounds containing a piperidine ring, which is a saturated aliphatic six-member ring with one nitrogen atom and five carbon atoms. Sedridine is soluble (in water) and an extremely weak acidic compound (based on its pKa). Sedridine can be found in pomegranate, which makes sedridine a potential biomarker for the consumption of this food product.
octanoate
Caprylic acid, or octanoic acid, with the structural formula CH3(CH2)6CO2H, is an eight-carbon straight-chain fatty acid and a carboxylic acid. It is an oily Liquid with a slightly unpleasant rancid taste and odor. It is minimally soluble in water. Caprylic acid can be found in numerous foods such as Prunus (Cherry, Plum), pineapple sages, black raspberries, shallots, coconuts and breast milk. Caprylic acid is taken as a dietary supplement. Caprylic acid is used commercially in the production of esters used in perfumery and in the manufacture of dyes. Caprylic acid is an antimicrobial pesticide used as a food contact surface sanitizer on dairy equipment, food processing equipment, breweries, wineries, and beverage processing plants. It is also used as disinfectant in health care facilities, schools/colleges, industrial facilities, recreational facilities, retail and wholesale establishments, livestock premises, restaurants, and hotels/motels. In addition, caprylic acid is used as an algicide, bactericide, fungicide, and herbicide in greenhouses and garden centers. Caprylic acid, and other fatty acids, affect the hunger hormone ghrelin. Ghrelin must be acylated, where it acquires an -OH group, before it can stimulate the hunger receptors in the hypothalamus. Caprylic acid becomes linked post-translationally to serine at the 3-position by the enzyme ghrelin O-acyltransferase (GOAT), located on the cell membrane of ghrelin cells in the stomach and pancreas (PMID 19896496). Caprylic acid affects those with medium-chain acyl-CoA dehydrogenase deficiency (MCAD), which is an inborn error of metabolism, marked by mutations of the gene ACADM. Those affected with MCAD have difficulties converting fatty acids to energy, especially during fasting. As a result, fatty acids build up and cause damage to liver and brain (PMID: 27536022). Octanoate radical, also known as caprylic acid or octanoic acid, is a member of the class of compounds known as medium-chain fatty acids. Medium-chain fatty acids are fatty acids with an aliphatic tail that contains between 4 and 12 carbon atoms. Octanoate radical is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Octanoate radical can be found in a number of food items such as soft-necked garlic, chicory, star anise, and grapefruit/pummelo hybrid, which makes octanoate radical a potential biomarker for the consumption of these food products. Octanoate radical can be found primarily in feces and urine. Moreover, octanoate radical is found to be associated with medium Chain Acyl-CoA Dehydrogenase Deficiency.
